Married couple Ami and David Mason have started vlogging about their sex life to help other couples that have a big age gap.
David, 60, is technically old enough to be 27-year-old Ami's grandfather but they think their relationship is so perfect and natural that they share their lovemaking tips on their own YouTube channel.
Speaking to The Sun, she said: "Sex with a 60-year-old is awesome and life changing and we're very open about our relationship. He is better than any guy my age."
The couple discuss everything from David's penis size, to oral sex and using Viagra, and Ami doesn't care if people don't accept the couple.
Ami said: "We have shocked many people because we openly discuss our fetishes, how we use condoms, the longest blow job I have given my husband and what we do in bed. It's instructional not pervy.
"If people find my love for David unacceptable I don't care. Yes to many it's shocking but to others it's awesome to hear us talking about spanking or fetishes. Sex at 60 and with a 60-year-old rocks."
